iClarified reported the numbers yesterday, also revealing that iOS 7 is still Apple's most popular operating system, boasting 49 per cent of its mobile portfolio.

Over recent days, statistics have given us the impression that iOS 8 hasn't quite piqued the interest of iPhone, iPad and iPod users in the same way that iOS 6 and iOS 7 did when they were first released.

However, these latest figures go some way to disproving this.

What's more, this rapid rate of adoption will hit arch-rival Google like a custard pie to the face. The latest version of its Android operating system, KitKat, has taken almost 11 months to reach the 24.5 per cent mark, according to the company's own figures.
